After eating fruit can not immediately take medicine, it is recommended that the best interval between fruit and medicine 1 hour is ideal. This is because most of the fruits contain acidic substances, after eating fruits will change the acid-base environment between the gastrointestinal tract, if you take drugs at this time will affect the role of drugs, leading to a decrease in drug metabolism enzymes, and may cause serious adverse side effects of drugs. Especially for lipid-lowering drugs, and some anti-allergy drugs, the effect of fruit may be more obvious. Therefore, it is recommended that the interval between fruit and medication should be about 1 hour, when the fruit has been basically metabolized and absorbed by the gastrointestinal tract, which will not affect the acid-base environment of the body, and then take the medication will be safer and will not affect the efficacy of the medication.
